Login fail using chatter oauth api with communities user name/password

hi,

 

We use new Customer Communities licenses, and the customers will be accessing the app through a native mobile
app(android and iOS).  We were told there was API access for communities but we have problem during logging into SFDC via Chatter API with Communities User's uname/password.  The document we refer to is http://www.salesforce.com/us/developer/docs/chatterapi/

The login fail error is {"error":"unsupported_grant_type","error_description":"grant type not supported"}.  The communities licenses user can login to the communities via browser but fail with OAuth.


Please help.

Did you look at the steps on portal authentication mentioned under section "Portal Authentication Using OAuth 2.0 and Force.com Sites" of Mobile SDK dev guide: https://github.com/forcedotcom/SalesforceMobileSDK-Shared/blob/master/doc/mobile_sdk.pdf?raw=true
